v "1922; j Serial x 601,156.

Be it known that I, FRANK a.'--citizen o f'the United States, and resi-'dent of the city OfNew York, borough of Manhattan, in the, county andState of New York, have invented a new and ImprovedCoffee-BrewingApparatus, of which the following is a full, clear, andexact description.

Among "the principal objects which the 1, present invention has in vieware: to provention, showing in conjunction therewith a 'vide means forbrewing cofi'ee or similar beverages for small consumption; to" purveysmall quantities of a table beverage for individual consumption; to varythe strength of said beverage; to provide for quickly'brewing a smallquantity of table beverage for individual consumption; and to proportionthe quantity of the material froln which the beverage is concocted to,the demand for the beverage.-

r :As'seen in the a drawings,'a rotary valve:

10 is placed in a tubular valvecasing 11, wherein port-s 12 and 13 areprovided-for establishing. communication between the water chamber 14and the brewing-chamber.

. 15,-'when the water controlling valve pas H. SIMoN'roN,

. sage is proper-ly disposed. The pan holdc1217 is cast from metal andis preferably integral with the valve casing 11. v, The container 16 ispreferably constructed of glass and is open at the bottom only, so as toprovide for an air space above the water '18, being" trapped andcompressed thereby as thew'ater enters and fills the-container; In

practice the full volume of air in the-con tainer 16 is compressed atthe upper end thereof, until the expansion force equals the headpressure of the wate entering. It is obvious that when the valve 10 isturned to place thewater channel 19 in communiof the water being :due tothe compressed air at the upper end of the chamber 16.

A pan 20has a spout 21 centrally 10- v catedtherein. The pan 20 has aninturned flange 22, the uppe surface of which is beveled to form a tightjoint with the lower edge of the holder 17., Theupper edge of the flange22 forms a rest for the outturned flange 23 of the circularside of thecup 24.

The cup 24 is furnished with a close meshed sieve. bottom 25, upon whichin practice the pulverized coffee rests. The

pan 20 is vremovably attached to the holder 17, hooks 27 being providedfor this purpose. shanks 2810f handles 29 rise on the upper edges ofthehooks 27, the said upper edges being slightly'inclined to wedge theinclined surface of the flange 22 into intimate contact with thelower-edge of the holder 17. When the pan 20 and the holder 17 are soconnected, the chamber 15 is tightly closed except through the coffee 26and spout 21.

Both water H and steam are delivered to thechambers l4 and 15. To thisend, two pipes'30 and'31 are provided. In service,

structure by any suitable :means. The pipe 30 is-connected with somesource of boiling water; The pipe-31 is connected with'a steam source..7

i The valve channels 19 and'33lare disposed The- - to' the chamber 15.

'or packed with pulverized coffee.

in the same vertical plane and may coincide with the opening of the pipe30 and the ports 12 and 13. The valve passage 34 is disposed in avertical plane incorporating the opening of'the steam pipe 31 and theport 35. As seen best in Fig. 3 of the drawings the port 35 is laterallydisposed with reference to the ports 12 and 13. The valve 10 has a stemto which is connected an operating handle 37.

Operation. The apparatus herein disclosed is designed primarily to meetthe needs of restaurants where coffee is one articles dispensed.

Great difficulty is experienced in satisfying the individual tastes of anumber and variety of customers. When equipped with a number ofapparatuses such as herein described, a number of; cups 24 are suppliedWhen a demand is made for coffee, thewaitress takes one of the packedcups and places it in the pan 20, To do this, she firstremoves the pan20 by rotating the cup to the position where the handle-s '29 becomedisengaged from the hooks 27. When the cup 24 is placed in the pan 20,said pan is again placed in supported relation to the holder 17, beingtightened by the hooks 27. The handle 37. is then turned from theposition shown in broken lines in Figure 1 to the position shown in fulllines in said figure.

of the. staple This latter position corresponds with the disposition'ofthe valve 10, as seen in Figures 2 and 4. It will be observed that inthis position, thelport channels 19 and 33 are in communication with thepipe 30 and with the chamber 14, while simultaneously the port channel34 has been placed in communicationwithpthe steam pipe'31 and thechamber 15. In these positions of the said port. channels, boiling wateris delivered to the chamber 14 and steam Water and steam continue flowsimultaneously until the water is arrested by the air pressure at thetop of the chamber 14. When the operator observes that the water hasceased flowing, she moves the handle37 to the position indicated bybroken lines in Fig; 1, which position is shown -best in Figures. 5 and6 of the .drawings.

channel 19 is disposed to permit the water 18 to flow from the chamber14 into the holder '17 and chamber 15 thereof to be spread on the plate38 and thence precipitated upon the coffee 26..

During the period in which water is admitted to the chamber 14, steam isintroduced into the chamber 15, with the effect that the coffee 26 inthe cup 24 is cooked or In this position, it will be observed: the steamsupply is discontinued while the preheated. When, now, the valve isturned so that the steam supply is discontinued j been placedthereunder.

If for any reason it 'is desired to further extract the essence orstrength of the coffee, the valve 10 is moved to the position shown inFig. 7 where the channel 39 is placed in communication with the steampipe 31 and the port 35. In this position of the valve,

the channels 34, 19 and 33 are out of register with any of the portsabove referred to and steam only is delivered through the valve and tothe chamber 15.

I/Vhen the individual brew has been completed, the cup 24 is removed andsuitable disposition is made of the coffee grounds.

From the foregoing it will be seenthat the functioning of the presentinvention consists in providing means for preliminarily introducingsteam into the body of the coffee for a definite period; thenintroducing heated water in predetermined quantity through the saidcoffee; and then again introducing steam into the body of the coffee.The result of the successive operations is that the body of the coffeeis first saturated with a hot steam which prepares it to the bestadvantage to receive the hot water, and after being acted upon by thesaid hot water, the second introduction of steam eliminates the waterfrom the body of the coffee.

While in the above specification I have described the container 16 andfunction thereof as a regulator for the amountof water to be used, itwill be understood that other means commonly known to the art, may beemployed for delivering to the body of coffee, the required amount ofwater without employing said chamber 16. Therefore I do not wish to' belimited toan apparatus employing the said chamber 16.
